An experimental insight into the advantages of in situ solvothermal route to construct 3D graphene-based anode materials for lithium-ion batteries

Three-dimensional self-assembled Fe2O3/graphene sheets composites as anode materials for lithium ion batteries are prepared by integrating in situ solvothermal (IS), ex situ solvothermal (ES) and in situ hydrothermal (IH) methods, which is used as an example to systematically clarify the interfacial interaction between Fe2O3 and graphene and further evaluate the benefits of in situ solvothermal synthesis strategy.
